CLI – This example configures an IPv6 gateway, specifies the
management interface, configures a global unicast address, and then sets
the MTU.
Configuring an IPv6 General Network Prefix
The IPv6 General Prefix page is used to configure general prefixes that are
subsequently used on the IPv6 Configuration web page (see page 4-13) to
specify the network address portion of an interface address.
Command Usage
• Prefixes may contain zero-value fields or end in zeros.
• A general prefix holds a short prefix that indicates the high-order bits
used in the network portion of the address. Longer, more specific,
prefixes can be based on the general prefix to specify any number of
